Maintaining the system over time
Leased systems are not owned by the homeowner or business drawing the power, but typically by a third-party. It’s like the landlord is supposed to keep up the rental unit. Sounds good, but listen to Consumer Reports:
Lease deals do cover any maintenance needed, to be sure. And a solar system will need some upkeep within the common, 20-year lease term. The question that Consumer Reports raises is a good one: Do the maintenance needs merit the increased expense of the lease?
Some products need regular service. A copy machine with a monthly lease and maintenance charge is a smart deal. But hey, there’s no paper to jam a solar array. No moving parts, at all.
The comparison on this point, therefore, is between leasing a product with limited maintenance needs, and owning the same with the protections offered by equipment warranties.
